Product features
Structural design
Foldable: It can be flattened during transportation and storage, saving space, and unfolded into shape when in use.
Buckle/snap design: No need for glue, fixed through structural self-locking (such as PP folding box).
Stackable: It can be stacked in multiple layers after folding or forming, optimizing storage.
Material characteristics
PP (polypropylene): lightweight, bend resistant, suitable for repeated folding (such as food containers).
PET (polyester): high transparency, good display effect (such as cosmetic trial packaging).
PVC (polyvinyl chloride): High rigidity, suitable for folding boxes with fixed shapes (such as electronic product liners).
Function expansion
Window design: Transparent PET displays the contents.
Handle/hanging hole: convenient for carrying or retail display.
Dust cover: Fold and seal to prevent dust (such as in express packaging boxes).
The main advantages of plastic folding boxes
Space saving folding reduces volume by 50% -70% and lowers logistics costs.
Durable and more resistant to pressure, water, and wear than paper folding boxes.
Reusable and supports multiple folding/unfolding, suitable for circular packaging scenarios.
Environmentally friendly optional materials (such as PP, PET) can be recycled or use recycled plastics.
Quick assembly without the need for glue, with a snap in design that enhances efficiency.
Important parameter characteristics
Material and thickness
Material characteristics, applicable scenarios, recommended thickness
PP (polypropylene) bending resistant, food grade takeaway food box, logistics box 0.3-1.2mm
PET (polyester) high transparency, tear resistant cosmetics, gift box 0.2-0.8mm
PVC (polyvinyl chloride) rigid, low-cost electronic product lining 0.5-1.5mm
Process and surface treatment
Die cutting indentation: Ensure accurate folding lines and avoid breakage.
Screen printing: suitable for logos and simple patterns.
Transparent/frosted effect: PET material can be treated on both sides.
Certification
Environmental certification (optional)
Food grade certification (FDA, EU 10/2011): used for food packaging.
Recyclable logo (such as PP triangle logo).
Proportion of recycled plastic (such as 30% PCR-PP).
Selection suggestions
Food contact → Choose food grade PP+FDA certification.
High transparency display → PET material+window design.
Heavy object transportation → thickened PP/PVC+reinforced rib structure.
Application industry
Features: Foldable gift box (Save over 50% space in transportation costs); Assembly efficiency: molding within 10 seconds (Reusable support for multiple folds)
